Creating this delicious Apple Bundt Cake is simple when following these clear steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 10-inch bundt pan with butter or non-stick spray.
2. Combine Dry Ingredients: In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking soda, baking powder, cinnamon, and salt until well combined.
3. Cream Butter: In another bowl, cream the softened butter with an electric mixer until light and fluffy, about 3-5 minutes.
4. Add Eggs and Vanilla: Add the eggs one at a time to the butter mixture, mixing well after each addition. Then, incorporate the vanilla extract.
5. Combine Mixtures: Gradually add the dry ingredient mixture to the wet ingredients, mixing until just combined. Be careful not to overmix.
6. Fold in Apples and Nuts: Gently fold in the chopped apples and, if desired, the walnuts or pecans, ensuring even distribution.
7. Pour Batter: Pour the batter into the prepared bundt pan, spreading it evenly.
8. Bake: Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Allow the cake to cool in the pan for 10-15 minutes before carefully inverting it onto a wire rack to cool completely.
10. Glaze (Optional): Once the cake is cooled, consider drizzling it with a simple glaze made from powdered sugar and a bit of milk for added sweetness.

Following these steps will lead you to an incredible Apple Bundt Cake that will delight everyone who tries it.
